Title:
  X fall in failsafe mode after install if nvidia restricted drivers are
  installed during LiveCD session in intrepid

Status in “nvidia-graphics-drivers-173” package in Ubuntu:
  Invalid
Status in “ubiquity” package in Ubuntu:
  Triaged

Bug description:
  New jockey 0.4+r345-0ubuntu1 can now install and enable restricted
  drivers directly from the intrepid a4 LiveCD, so people can test
  nvidia drivers and compiz even before installing ubuntu.

  However, when doing this, a more important problem happens. If nvidia
  drivers are installed during the LiveCD session, once the computer has
  rebooted to the new intrepid installation, X will fails to start and
  fall to safe mode. Strangely, almost all changes that has been made
  inside the LiveCD session seems to have persisted. nvidia-* packages
  are all marked as installed in synaptic and /etc/X11/xorg.conf is
  already configured to use proprietary nvidia driver (Driver
  "nvidia" Option "NoLogo"        "True").

  This problem will always reproduce, regardless of the number of
  reboot. It's possible to fix this problem with a simple re-
  installation of all "nvidia-*" packages in synaptic, after what X
  really uses nvidia driver.

  Steps to reproduce :
  1. Have a computer with a nvidia card which needs nvidia restricted drivers.
  2. Boot intrepid alpha 4 LiveCD
  3. Inside the LiveCD session, install nvidia drivers through Hardware Drivers and reload X with CTRL + ALT + Backspace
  4. Install Ubuntu and reboot

  Results :
  The freshly installed ubuntu intrepid a4 will boot, but X will fail 3 times to load and then fall in failsafe mode.
